Understanding the dynamics of magmatic systems is a fundamental goal in volcanology. Magma fluxes and residence times in magma chambers are important parameters that need to be estimated if predictive models of eruption are to be developed. One powerful approach is to use reaction textures or chemical diffusion profiles to assess the duration of magma-mineral interaction by coupling these observations with experimental data on reaction kinetics. This study combines a field study of the volcanic centre at Rockeskyller Kopf, West Eifel, with subsequent experimental work to calibrate reac-tions that are directly applicable to these rocks. Mapping will establish the volcanic history and pro-vide a framework for sampling from units related to successive eruptive events. Analytical data from the natural samples will be combined with experimental results to model contact-times between miner-als and melt, and therefore assess magma residence times at a number of stages during the lifespan of the volcanic centre at Rockeskyller Kopf.

了解岩浆系统的动力学是火山学的一个基本目标。如果要建立预测喷发的模型，就需要估计岩浆流量和岩浆房中的停留时间等重要参数。一个强大的方法是使用反应纹理或化学扩散配置文件，以评估岩浆-矿物相互作用的持续时间，将这些观察与反应动力学的实验数据相结合。这项研究结合了在Rockeskyller Kopf，西艾菲尔火山中心的实地研究，随后的实验工作，校准反应，直接适用于这些岩石。制图将确定火山的历史，并为从与连续喷发事件有关的单位取样提供一个框架。来自天然样品的分析数据将与实验结果相结合，以模拟矿物和熔体之间的接触时间，从而评估Rockeskyller Kopf火山中心寿命期间多个阶段的岩浆停留时间。
